One patient is still in hospital in Brisbane after suffering major blood loss when one of his arteries was nicked during surgery and it went unnoticed.

It's alleged another patient had a testicle removed unnecessarily after he was misdiagnosed, and it's believed another person had a stent inserted in the wrong place.

Those patients don't need further treatment at this stage.

Charles Ware is the chairman of the Central Queensland Hospital and Health Board that manages the hospital.

He says this case is very different to the issues with foreign-trained doctors in the past.

CHARLES WARE: It's not a Patel. I mean, nobody's died; there's no cover up; we've been open and, as I said to you, this board doesn't do cover up; we don't do denial; I don't do cover up and I don't do denial, so we've identified the problem; we've dealt with it and we're now addressing the broader systemic issues.

But technically, he's been stood down on full pay, pending the outcome of the investigations.

The surgeon was qualified as a urologist in Spain, then spent another two years to get Australian qualifications.

The Labor MP for Rockhampton Bill Byrne quizzed the Queensland Health Minister Lawrence Springborg about the doctor in State Parliament.

BILL BYRNE: Will the Minister advise when he first became aware of these problems, and what he did immediately about them?

LAWRENCE SPRINGBORG: I thank the Honourable Member for Rockhampton for his question. We have a very different process of dealing with this than previous times past, where there was another incident or other incidents just south of where the Honourable Member represents, where the matters were actually swept under the carpet, involved a lot more people Madame Speaker and actually required a nurse whistle blower.

Nobody was actually stood aside and the person responsible was given a business class airfare out of the country.

Now, what we actually see with regards to this, Madame Speaker, what we see with this Madame Speaker, is the circumstance where the Hospital and Health Board became aware of this, as I understand, early last week, stood the surgeon down and actually started its own process of investigation.

STEPHANIE SMAIL: Doctor Antonio Vega Vega is a Visiting Medical Officer, and could still work in the private hospital system.

But in a statement, the Mater Hospital in Rockhampton says he has volunteered to suspend his work there.

The statement says the doctor has treated more than 800 patients at the hospital since 2011, with no unusual or concerning clinical outcomes.

The Australian Health Practitioner Regulation Agency, which supervises the registration of doctors qualified to practice, says it's seeking more information.
